We have 3 AquaGlass shower stalls, the kind that are enclosed with the ceiling as part of the stall.They are 11 years old. I was given a product called AquaGloss to clean the stalls with. It was in a metal can and you wiped it on, let it dry, then wiped it off. Sort of like a car wax. It cleaned thestalls well and kept them looking great. I did this to the ones that were used regularly every sixmonths or so, touching up in between with Scrubbing Bubbles. I have been unable to find theAquaGloss or any similar product. And AquaGlass is less than helpful is finding another product.What can you recommend that is long lasting and a truly deep-cleaner?Thanks.
